ABSTRACT:
A receiver capable of receiving a plurality of different codes at a plurality of different frequencies is set forth herein. The receiver offers digital frequency control by using a controller driven signal diode to add or remove capacitance to or from a band pass filter circuit, thereby altering the frequency the bandpass filter is setup to receive. Input devices allow the receiver code, bit pattern, and relay output to be selected among a plurality of different codes, bit patterns, and relay output types. The receiver processes the selections, determines what frequency receiver actuation signal is to be received, and alters the bias of the signal diode to adjust the bandpass filter frequency accordingly.
